Long-term follow-up of total penile reconstruction with sensate osteocutaneous free fibula flap in 18 biological male patients

Surgical reconstruction of the penis is challenging because of the many cosmetic and functional (e.g., sexual intercourse and voiding) requirements that must be addressed. Since the free sensate osteocutaneous fibula flap was first described for total penile reconstruction in 1993 it has been widely accepted, with its advantages and minimal shortcomings. In this article, the authors present the longest follow-up of biologically male patients with free fibular phalloplasties. Since 1994, 18 biologically male patients with total penile losses for various reasons were treated with free sensate osteocutaneous fibula flaps. All patients were included in the study. The ages of the patients ranged between 20 and 26 years (mean, 22.2 years). The average follow-up period was 5.4 years (range, 1 to 9 years). Patient satisfaction was evaluated by a questionnaire regarding both quality of orgasm and daily activities. Conventional radiographic imaging, magnetic resonance imaging, and bone mineral densitometry were performed to evaluate the fate of the bony component of the flap. Also, sensibility was evaluated by bulbocavernous reflex and penile somatosensory evoked potentials testing in nine patients. Six patients married, and five of them had six children. Most patients and their partners reported pleasurable sexual intercourse and orgasm. Conventional radiographs of the fibular bone in neophalluses showed robust, calcified bone structure without any evidence of bone resorption or fracture. The magnetic resonance images showed the cortical substance and spongiosum of the bone marrow, which are characteristic signs of bone viability. After intravenous injection of gadolinium, the neophallus bone showed uptake of contrast medium. Viability of neophallus bone was shown even at 9-year follow-up (the longest follow-up in the literature). Dual energy x-ray absorptiometry measurements of the penile bone grafts showed that fibular components in the penis had bone mineral density values that were close to but lower than those of intact fibula in the same subjects. These results were considered as evidence of viability of bone grafts. Neural integrity was found between the nerves of the neophallus and the residual penile bodies by both bulbocavernous reflex and penile somatosensory evoked potentials tests. In conclusion, free sensate fibula flap phalloplasty provides the cosmetic and functional requirements that an ideal penis should have. All results put an end to the discussion that the fibular component of the neophallus could resorb. Constitution of neural integrity is important in terms of pleasurable sexual intercourse. The authors believe the free sensate osteocutaneous fibula flap should be considered as the standard in penile reconstruction.     

Effects of 24-epibrassinolide on seed germination, seedling growth, lipid peroxidation, proline content and antioxidative system of rice (Oryza sativa L.) under salinity stress

The effects of 24-epibrassinolide (24-epiBL) on seedling growth, antioxidative system, lipid peroxidation, proline and soluble protein content were investigated in seedlings of the salt-sensitive rice cultivar IR-28. Seedling growth of rice plants was improved by 24-epiBL treatment under salt stress conditions. When seedlings treated with 24-epiBL were subjected to 120 mM NaCl stress, the activities of superoxide dismutase (EC 1.15.1.1), catalase (EC 1.11.1.6) and glutathione reductase (EC 1.6.4.2) did not show significant difference, whereas the activity of ascorbate peroxidase (EC 1.11.1.11) significantly increased. Increased activity of peroxidase (EC 1.11.1.7) under NaCl stress showed remarkable decrease in the 24-epiBL+NaCl-applied group. Lipid peroxidation level significantly increased under salt stress but decreased with 24-epiBL application revealing that less oxidative damage occurred in this group (24-epiBL+NaCl). In addition, increased proline content in the NaCl-applied group was decreased by 24-epiBL application in the 24-epiBL+NaCl-applied group. Soluble protein content was increased by 24-epiBL application even under NaCl stress, being also higher than control conditions (no 24-epiBL or NaCl treatment). 24-epiBL treatment considerably alleviated oxidative damage that occurred under NaCl-stressed conditions and improved seedling growth in part under salt stress in sensitive IR-28 seedlings.     

Experimental studies on bacterial product cantastim derived from Pseudomonas aeruginosa. VI. Protection in tolerant mice

Endotoxin tolerance is defined as a hyporesponsiveness state to a second stimulation with lipopolysaccharide (LPS). This refractory state is primarily associated with an attenuated cytokine production. Whether this down-regulation of cytokine production results in an increased susceptibility to infection remains a matter of controversy. The aim of this study was to investigate the resistance of tolerant mice to a subsequent bacterial infection and the role of bacterial immunomodulator CANTASTIM (CS) in this experimental model. We have shown that the LPS-tolerant mice (intraperitoneally inoculated with LPS Salmonella typhimurium 10 microg/mouse, daily for two days) were protected against a challenge with Pseudomonas aeruginosa (LD 100) administered 24 h later. On the contrary, when the animals were challenged 1 h after the last LPS injection, they did not survive. However if these animals were pre-treated with CS 3 days before LPS treatment, they became resistant to a subsequent bacterial challenge. More interestingly, if the treatment with LPS was substituted with CS (same schedule, route of administration and doses) there was a significant increase in the survival of mice challenged with Pseudomonas aeruginosa after either 1 h or 24 h. In this case, the increase in the rate of survival was correlated with an enhanced production of IL-10 in the peritoneal cavities of CS treated mice as compared to LPS treated mice.     

A review of 35 cases of asymmetric crying facies

A review of 35 cases of asymmetric crying facies: Congenital asymmetric crying facies (ACF) is caused by congenital hypoplasia or agenesis of the depressor anguli oris muscle (DAOM) on one side of the mouth. It is well known that this anomaly is frequently associated with cardiovascular, head and neck, musculoskeletal, respiratory, gastrointestinal, central nervous system, and genitourinary anomalies. In this article we report 35 ACF patients (28 children and 7 adults) and found additional abnormalities in 16 of them (i.e. 45%). The abnormalities were cerebral and cerebellar atrophy, mega-cisterna magna, mental motor retardation, convulsions, corpus callosum dysgenesis, cranial bone defect, dermoid cyst, spina bifida occulta, hypertelorism, micrognatia, retrognatia, hemangioma on the lower lip, short frenulum, cleft palate, low-set ears, preauricular tag, mild facial hypoplasia, sternal cleft, congenital heart defect, renal hypoplasia, vesicoureteral reflux, hypertrophic osteoarthropathy, congenital joint contractures, congenital hip dislocation, polydactyly, and umbilical and inguinal hernia. Besides these, one infant was born to a diabetic mother, and had atrial septal defect and the four other children had 4p deletion, Klinefelter syndrome, isolated CD4 deficiency and Treacher-Collins like facial appearance, respectively Although many of these abnormalities were reported in association with ACF, cerebellar atrophy, sternal cleft, cranial bone defect, infant of diabetic mother, 4p deletion, Klinefelter syndrome, isolated CD4 deficiency and Treacher-Collins like facial appearance were not previously published.     

Morphological characteristics and performance variables of women soccer players

The purpose of this study was to describe certain morphological characteristics of women soccer players and to examine aspects of training and performance. Twenty-two anthropometric sites were used in measurements of somatotype and body composition; flexibility, agility, anaerobic power, leg muscle power, and dynamic pulmonary functions were used as performance variables. Measurements were made on 17 professional athletes and 17 age-matched sedentary women who acted as controls. The women soccer players showed less fat content and less lean body mass than did the sedentary women. The mean somatotype for the soccer players was 3.07-3.55-2.43 and for the nonathletes was 3.57-3.35-2.90. Anaerobic power, leg muscle power, and agility in the athletes were higher than in the nonathletes, whereas no differences were found in flexibility and pulmonary functions (p > 0.05). The women soccer players showed more significantly mesomorphic, less endomorphic, least ectomorphic components and higher performance level than did the sedentary women.     

Effect of regular training on plasma thiols,malondialdehyde and carnitine concentrations in young soccer players

Physical activity is known to induce oxidative stress in individuals subjected to intense exercise. Contrarily, there are enzymatic and nonenzymatic defence systems against oxygen radicals in aerobic organisms. Sulphydryl groups such as thiol and glutathione (GSH) can be given as an example to non-enzymatic low molecular weight antioxidants. Carnitine may be related to the performance enhancement in high intensity intermittent exercises and might probably improve the aerobic capacity by stimulating lipid oxidation in muscle cells during long term exercise. But, the effects caused by this supplement during physical activity have not been fully described in the literature. The aim of the study was to compare plasma thiols (PSH), malondialdehyde (MDA) and carnitine levels and maximal oxygen uptake (VO2(max)) of the soccers under regular training with the values of the healthy controls. Our results demonstrates that soccers seem to be under less oxidative stress, as their MDA levels were significantly lower (P < 0.001) when compared with the control group while their PSH levels were significantly elevated (P < 0.001), during resting condition. In addition, the plasma carnitine concentrations of the soccer group yields lower values while the VO2(max) yields a higher value when compared with the control group. The differences between the soccer and the control groups are significant (for both, P < 0.001). The present research reveals the fact that regular soccer training shows beneficial effect on decreasing of lipid peroxidation levels. Furthermore; the sportsmen who are under intense training programs have low plasma carnitine values which do not cause negative effect on their sportive performance.     

Acute effect of hemodialysis on serum levels of the proinflammatory cytokines

Chronic inflammation is a common feature of end-stage renal disease, which carries a heightened risk of atherosclerosis and other co-morbid conditions. Dialysis treatment per se can bring additional risk factors for inflammation, such as increased risk of local graft and fistula infections, impure dialysate or bio-incompatible membranes. Our study was designed to determine whether a hemodialysis session leads to an acute substantial alteration in the plasma levels of the proinflammatory cytokines interleukin (IL)-6, IL-1beta and tumor necrosis factor (TNF)-alpha, the T-lymphocyte activation factor soluble IL-2 receptor (sIL-2R), and an inflammation mediator and chemotactic granulocyte factor, IL-8, in end-stage renal disease patients receiving chronic intermittent HD. In this study, 21 (12 male/nine female) patients undergoing chronic hemodialysis were enrolled. The acute effect of a hemodialysis session on serum cytokine concentrations was assessed by comparison of pre-hemodialysis and post-hemodialysis determinations. Serum IL-1beta, sIL-2R, IL-6, IL-8 and TNF-alpha levels were determined with chemiluminescence enzyme immunometric assays. A significant difference was not observed for IL-1beta, IL-6, TNF-alpha, and sIL-2R concentrations in pre-hemodialysis and post-hemodialysis specimens (p>0.05). Serum median (25th-75th percentiles) IL-8 concentration was 69.4 (34.9-110.3) pg/ml before hemodialysis, and decreased to 31.5 (18.0-78.8) pg/ml following hemodialysis (p: 0.006). Clearance of IL-8 increased by 0.47+/-0.08 pg/ml for each unit increase in pre-dialysis IL-8 (p<0.001) and decreased by 5.63+/-2.59 pg/ml for each unit increase in pre-dialysis urea mmol/l (p<0.05). In conclusion, the results of our study demonstrate that a hemodialysis session markedly decreases IL-8 concentration, which is significantly affected by pre-dialysis concentrations, indicating that removal of IL-8 is a concentration gradient-dependent action, but does not change the serum levels of IL-1beta, sIL-2R, IL-6, and TNF-alpha, underlining importance of the structural characteristics of the molecules.     

A rare cause of short stature: Leri Weill dyschondrosteosis

Short stature is a common pediatric problem. It may occur rarely as a result of genetic disorders. Leri-Weill dyschondrosteosis (LWD) is one of the rare genetic disorders of skeletal system resulting with short stature. It is characterized by shortness of stature and Madelung deformity of the wrist. Here we report a case of LWD with some skeletal stigmas of Turner syndrome. She has also depressed medial tibial condyles that to our knowledge, has not previously been reported in LWD.
